图3是实施例2全印刷光电探测器制备过程中的扫描电镜图,其中A图为柔性基底的扫描电镜图,B图为柔性基底上印刷银电极后的扫描电镜图,C图为在带有银电极的柔性基底上印刷一层硫化铋纳米线浆料的扫描电镜图,D图为全印刷光电探测器在扫描电镜下的侧视图。相较于A图,B图和C图表面电极和材料在柔性基底上的附着力良好,由图D可知硫化铋纳米线浆料的厚度达80μm。
图4是实施例2全印刷光电探测器的光响应测试原理图及其在不同斩光盘转动频率下的i-t曲线图,其中,A图为全印刷光电探测器的光响应测试示意图,B-D图为全印刷光电探测器分别在斩光盘频率为10Hz、50Hz、200Hz时的i-t曲线图。测试在一个太阳光强度的氙灯照射和没有施加外界电压的条件下完成,脉冲入射光来自斩光盘的快速转动,并且测试在空气环境下进行,表面硫化铋纳米线具有不错的稳定性。如图所示,有光条件下比暗态时电流明显增大(测试从暗态开始),且响应速度小于2ms,说明硫化铋纳米线可以对光信号作出快速反应,是制备光电传感器良好的材料。
图5是实施例2全印刷光电探测器在暗态和不同波段的光照射下以及不同强度的光照射下的I-V曲线图,其中,A图为在暗态和不同波段光照射下全印刷光电探测器的I-V曲线图,B图为在暗态和不同强度光照射下全印刷光电探测器的I-V曲线图。A图中各个波段光的强度分别是2.35mW cm-2(blue laser),2.38mW cm-2(green laser),2.32mW cm-2(redlaser),电压变化在-2V到2V之间。比较A图中暗态和有白光照射的情况可知,全印刷光电传感器的电导率有明显增加,显然,光照会把电子从价带激发到导带而增大硫化铋纳米线的电导率;图中I-V曲线符合欧姆定律,这表明器件中电极与浆料本身及它们的连接所造成的电阻可以忽略不计。由B图及其插图可知,器件的电导率依赖于光照强度的增加而增加。
需要说明的是,本发明中,硫化铋纳米线制备、硫化铋纳米线浆料制备、丝网印刷电极及浆料的具体步骤及参数均可按公知常识作出相应调整。
最后说明的是,以上优选实施例仅用以说明本发明的技术方案而非限制,尽管通过上述优选实施例已经对本发明进行了详细的描述,但本领域技术人员应当理解,可以在形式上和细节上对其作出各种各样的改变,而不偏离本发明权利要求书所限定的范围。
